Definitions
- the present invention relates to an electromagnetic valve comprising a solenoid portion and a valve portion, and in particular to improvement of an end cover which closes a valve hole of the valve portion.
- a known electromagnetic valve which is disclosed in US 5441233 and shown in Fig. 3, comprises a bobbin 2 on which a coil 1 is wound, a fixed iron core 3 which is fitted into a central hole of the bobbin 2, a movable iron core 4 which is slidably inserted in the bobbin 2, valve seats 5a, 5b which are provided in a communication path which causes a plurality of ports (not shown) provided in a valve body 5 to communicate with one another, and valve members 6a, 6b which are driven by the movable iron core 4 to close the valve seats 5a, 5b.
- valve hole 7 for accommodating the valve member 6b is bored in the valve body 5, and an end cover 9 is fitted in an opening portion of the valve hole 7 which closes the opening portion and which serves as a valve seat for a valve spring 8 biasing the valve member 6b in one direction.
- the end cover 9 comprises a cylindrical base body portion 9a with a bottom, a plurality of engagement pieces 9b which extend from an outer peripheral face of the base body portion 9a in a direction opposite to the fitting direction of the end cover 9 and which are provided at their distal ends with claw portions 9c, and a seal member 10 which is disposed nearer to an outer periphery on the side of a distal end of the base body portion 9a than the engagement pieces 9b.
- the seal member 10 cannot be disposed nearer to the bottom of the base body portion 9a than the engagement pieces 9b and they must be disposed on the distal end side of the base body portion 9a. This lengthens the end cover 9 which prevents small-sizing of the electromagnetic valve. Also, since the engagement pieces 9b are bent along an outer peripheral face of the base body portion 9a, when the engagement pieces are shortened as far as possible in order to minimise the valve body 5, they have relatively high rigidities against an external force applied from a side direction thereof so that they become difficult to flex. Accordingly, when the end cover 9 is fitted into the valve hole 7, a relatively strong force is required.
- An object of the present invention is to provide an electromagnetic valve where a valve body can be small-sized and fitting into a valve hole can easily be performed.
- EP 1284383 discloses an electromagnetic valve provided with a valve portion having a valve body for switching flow paths by moving relative a valve seat in a housing and a solenoid portion for driving the valve body.
- the housing is formed from electrically insulating synthetic resin.
- a current conduction terminal constituting a current conduction system of the solenoid portion is inserted into a terminal insertion hole opened on a face of the housing which adjoins the solenoid portion.
- An opening is provided in the housing through which contact terminal extend to the current conduction terminal in the terminal insertion hole to be electrically connected thereto.
- the invention provides an electromagnetic valve comprising a valve portion having a valve body provided with a plurality of ports, a valve hole communicating with the ports and formed so as to be opened to an end face of the valve body, a valve member for switching flow paths between the ports located in the valve hole, an end cover for closing an opening portion of the valve hole and a solenoid portion which drives the valve member, wherein the valve body has at least one engagement groove having a first dimension extending in an axial direction of the valve hole and a stepped portion formed inside the engagement groove, and the end cover comprises a lid plate which covers the opening portion of the valve hole, a cylindrical portion provided on an inner face of the lid plate to be fitted in the valve hole in an air-tight manner, at least one arm piece which extends from the lid plate, a resilient engagement piece which extends from the arm piece along the engagement groove, and an engagement claw formed at the distal end of the resilient engagement piece to be engaged with the stepped portion of the engagement groove, characterised in that there are two engagement grooves one on each side of the opening portion
- An electromagnetic valve shown in Fig. 1 comprises a solenoid portion 10 and a valve portion 20.
- the solenoid portion 10 comprises a bobbin 13 on which a coil 12 has been wound, a magnetic case 11 which is provided around the coil 12 and which comprises a side wall having a generally rectangular sectional shape, an end wall formed on one end of the side wall integrally therewith and an opening formed on the other end thereof, a magnetic plate 16 which is arranged on the opening side of he magnetic case 11 in the bobbin 13, a column-shaped movable iron core 15 whose section is generally elliptic or oval and whose one end side is slidably inserted into a central hole extending the magnetic plate 16 and the bobbin 13 from the side of the magnetic plate 16, and a column-shaped fixed iron core 14 whose section is generally elliptic or oval, which is disposed on the end wall of the magnetic case 11 to be inserted in the central hole of the bobbin 13 and which attracts the movable iron core 15 by magnetic force.
- a stopper 17 which is made from synthetic resin and which abuts on the magnetic plate 16 when the movable iron core 15 is attracted to the fixed iron core 14 is pressure-fitted into the other end side of the movable iron core 15, and a return spring 18 is confined between the stopper 17 and the magnetic plate 16.
- the movable iron core 14 is separated from the fixed iron core 14 by the biasing force of the return spring 18 to move in a direction of pushing a push rod 19 of the valve portion 20 described later.
- the fixed iron core 14 attracts the movable iron core 15 by the magnetic force against the biasing force of the return spring 18 so that the pushing force of the movable iron core 15 to the push rod 19 is released.
- the valve portion 20 comprises a valve body 21 whose transverse face is generally rectangular and which has an input port P, an output port A, a discharge port R and a valve hole 21a which communicate with these ports, a movable orifice member 23 and a poppet valve 21 which are received in the valve hole 21a, and the push rod 19 which protrudes in one end of the valve portion 20 in a state where it is coupled to the poppet valve 22 and which is pushed by the movable iron core 15.
- the movable orifice member 23 comprises a supply valve seat 23a which is opened in the valve hole 21a to be opened/closed by the poppet valve 22, and a flow path 23b which causes the supply valve seat 23a and the input port A to communicate with each other, and it is provided within the valve hole 21a slidably in a direction of the poppet valve 22, or in a direction in which the supply valve seat 23a seats on the poppet valve 22.
- the poppet valve 22 is arranged within the valve hole 21a movably between a discharge valve seat 21d which causes the discharge port R to communicate with the valve hole 21a and the supply valve seat 23a, and it opens/closes both the valve seats 21d, 23a at a time of excitation to the coil 12 of the solenoid portion 10.
- a poppet spring 24 is confined between the movable orifice member 23 and the poppet valve 22.
- a hole end 21e which is opened to an end face of the valve body 21 for inserting the movable orifice member 23, the poppet valve 22 and the like in the valve hole 21a is tightly closed by an end cover 30 attached around it with a seal member 25.
- the solenoid portion 10 and the valve portion 20 are coupled to each other by fitting one end of the valve body 21 in the valve portion 20 from which the push rod 19 protrudes into an opening of the magnetic case 1 in the solenoid portion 10 via seal members 26 and 27.
- the movable iron core 15 separates from the fixed iron core 14 to push the poppet valve 22 to the supply valve seat 23a of the movable orifice member 23 via the push rod 19. Also, when the coil 12 is excited, the movable iron core 15 is attracted to the fixed iron core 14, so that pushing of the push rod 19 effected by the movable iron core 15 is released, and the poppet valve 22 is separated from the supply valve seat 23a and is seated on the discharge valve seat 21d by the biasing force of the poppet spring 24.
- the input port P, the output port A, and the discharge port R are put in communication with each other or are put in a disconnect state from each other so that switching is performed.
- the end cover 30 is constituted by a lid plate 31 which closes the end portion of the valve hole, arm pieces 31a which are provided so as to extend integrally from a peripheral edge portion of the lid plate 31 in both left and right directions and to be positioned in the same plane as the lid plate 31, resilient engagement pieces 32 which are formed integrally at end portions of the arm pieces 31a to extend vertically towards an inner face of the lid plate 31, and a cylindrical fitting portion 34 which is formed integrally on an inner face of the lid plate 31 and has a seal member 25 on the outer periphery and which is fitted into the hole end 21e of the valve hole 21a.
- Each resilient engagement piece 32 is integrally formed with an engagement claw 33, and the engagement claw is provided with a taper portion 33b expanding outward of the end cover 30 and a corner portion 33a engaged with a stepped portion 21c of an engagement groove 21b provided in the valve body 21.
- the height of the cylindrical fitting portion 34, from an inner face of the lid plate 31 is less than the resilient engagement pieces 32. Also, a recessed portion 34a is defined by the cylindrical fitting portion 34 and the lid plate 31 and one end portion of the movable orifice member 23 is slidably fitted into the recessed portion. A ventilation hole (not shown) is formed on the end cover 30 which causes the recessed portion 34a and the outside of the valve member 20 to communicate with each other.
- the poppet valve 22 constitutes a flow path opening/closing mechanism which opens/closes the supply valve seat 23a and the discharge valve seat 21d alternately together with the moveable orifice member 23 displaced in the valve hole.
- the flow path opening/closing mechanism is not limited to the illustrated arrangement.
- the movable orifice member 23 can be provided fixedly inside the valve hole or to the end cover 30.
- Engagement grooves 21b in which the resilient engagement pieces 32 are inserted for engagement are provided on both left and right outside positions of the hole end 21e in the valve body 21, and stepped portions 21c which are engaged with the engagement claws 33are formed on side walls outside of the engagement grooves 21b.
- the stepped portions 21c are formed by providing the engagement grooves 21b in a recessed manner on both sides of the opening portion of the hole end 21e in the valve body 21 and boring a through hole 21f intersecting the engagement grooves 21b from the outer face of the valve body 21.
- one end portion of the movable orifice member 23 is fitted into the recessed portion 34a.
- two arm portions 31a extend from the lid plate 31 of the end cover 30.
- the engagement claws 33 are formed on the outsides of the resilient engagement pieces 32, but they may be formed on insides thereof, of course.
- the end cover is constituted by a lid plate, a plurality of arm pieces which extend from a peripheral edge of the lid plate, resilient engagement pieces which are formed at their distal ends with engagement claws and expand in a taper shape, and a cylindrical fitting portion which is provided on an inner face of the lid plate in a projecting manner such that its height from the inner face is lower than that of the resilient engagement pieces and which has a seal member 25 on its outer periphery, a seal member can be disposed at a position nearer to the lid plate than the engagement claws of the engagement resilient pieces, so that the entire length of the end cover can be shortened and the electromagnetic valve is small-sized as compared with the conventional one. Also, since the arm pieces and the engagement pieces are easy to flex when the valve hole is closed by the end cover, the engagement claws can be caused to engage the stepped portions formed in the engagement grooves of the valve body with a smaller force than is required with the known valve.
